EVO takes flight in BMW's sultry i8

Electric cars and hybrids are here to stay, much to the apparent dismay of some auto enthusiasts, but that doesn't mean they have to represent the death of enjoyable driving. Granted, the initial run of hybrids in the US like the Honda Insight and Toyota Prius weren't exactly tailor-made for aggressive folks behind the wheel, but things are clearly changing. In its latest video, Evo takes a look at three examples from Europe's new crop of electrified vehicles to show that the future of fun motoring is safe and sound.
Evo editor Henry Catchpole kicks things off with one of the most bizarre EVs of the bunch, the tiny Renault Twizy. Its low power and 50-mile-per-hour top speed might make it miles away from a hot hatch, but there's still fun to be had in extracting the most from this little city car. Next up is the Audi A3 E-Tron, which isn't technically available yet. It's a step in the right direction of eventually creating an affordable, fun-to-drive hybrid hot hatch.
However, the main event is Catchpole getting some seat time in the BMW i8. The Bimmer can really fly -literally in this case - and the butterfly-door coupe offers a clear look at the prospects for electrified sports cars. It might not have the power of hybrid supercar contemporaries like the LaFerrari or Porsche 918 Spyder, but the BMW doesn't cost nearly as much, either. See? Improved efficiency doesn't have to mean boring.

2015 Audi A3 TDI Challenge

I officially gave up after 758 miles. The 15 or so miles leading up to this decision were spent in the right lane of Southern California's I-8 freeway, hazard lights blinking, climbing uphill at just over 40 miles per hour. After two days of sweating to the oldies (okay, a mix of SiriusXM Classic Rewind and First Wave), I had covered those 758 miles in a 2015 Audi A3 TDI on one tank of diesel fuel. And when I say sweating, I mean it quite literally. In order to maximize fuel efficiency, my co-driver and I kept the air conditioning off, even when the direct sunlight in the California desert had outside temperatures hovering around 90 degrees. I had been doing this hypermiling exercise for two days, the car was getting stinky, and I was ready to hear the sweet "thhhhhhhwack" of satisfaction that would finally come from peeling my sweat-soaked self off the A3's leather seat. Sexy, I know.
Audi had challenged me to drive 834 miles from Albuquerque, NM to San Diego, CA, on just one 13.2-gallon tank of diesel fuel. If you believe the EPA's highway fuel economy rating of 43 miles per gallon, this means I should have sputtered to a stop after 568 miles. But I went a grand total of 758 - that's 59.4 mpg - and I could have kept going. In fact, two teams made it the full 834 miles on their one allotted tank of fuel. That's over 63 mpg. That's twenty miles per gallon better than EPA estimates.
The TDI Challenge took me through three states over the course of two days, and the 834-mile journey wasn't just a simple highway cruise. I negotiated uphill climbs, long series of involving switchbacks through the mountains and elevations that ranged from 220 feet below sea level to nearly 8,000 feet above. I learned that super-crazy-efficient driving like this an incredibly challenging game that takes serious skill. But I also learned that if you're going to attempt to stomp all over the EPA's numbers, the Audi A3 TDI is one heck of a car for the journey.

Audi moves to patent electric Quattro and active-shutter wheels

Audi might have a few tricks up its sleeve for the coming years, with the Brits at Autocar uncovering a pair of patent filings made by the German luxury brand. The first is something we've seen before - wheel flaps - while the second is an evolution of one of Audi's trademark technologies.
We last saw wheel flaps on the Ford Atlas Concept in 2013, but the futuristic fuel-saving tech has so far failed to arrive on a production car. Audi may be seeking to change that, patenting the flaps that open and close automagically based on airflow. They can also open if the brakes get too hot.
The second patent is an evolution of Audi's Quattro all-wheel drive. The new AWD system uses an electrically driven rear axle and wheel sensors to figure out when and at which corner the car might lose traction, and is targeted largely at hybrid offerings, which is a field Audi has only recently dipped its toe into.
